Applicatinled June 13,

To all 'u1/0m 'it may concern.'

Be it lrnovvn' that I, ARTHUR Goonma citi- Zen oi the United Statesj residingat San Saba7 in the county of San Saba and Sta-te ot Texas, have invented `certain. new and useful Improvements in HarrowA Attach.- ments for Cultivators, oit which the following is a specification.

This invention relates to agricultural implements and has for its object the provision of an attachment 'lor cultivators by the use oi which the surface soil may be thoroughly pulverized and reduced to a iine `mulch and whereby all Weeds, `leaves or other trash may p be removed from the rows of growing plants or from the lines in Winch seed is tobe planted. The inventionseelrs` to provide an attachment for cultivators 'which may vhe' readily adjusted to any desired angle in both vertical and horizontal planes and which may be readily removed from or applied to a cultivator trame. Other .incidental objects of the invention will appear inthe course oi? the 'following description and the invention resides in certain novel features which Will be particularly pointed out in the appended claims.

ln the accompanying drawings- Figure l is a perspective view of a cultivator having my improved harrow attach ment applied thereto; l

Fig. 2 is an enlarged 'front elevation ot the attachment; y

Fig. 3 is a View, partly in end elevation and partly in vertical section, ot the barrow attachment g 4l: is a detail. perspective viewv show ing the means whereby the barrow teeth are secured in position. y

The cultivator l may be ot any Well-l nown or preferred type and my invention contemplates the provision of a harrow attachment 2 to each cultivator beam 3 adjacent the front end of the beam. The cultivator shovels l may be omit-ted and the attachment used solely for harrowing when desired. In carrying outI the invention, l employ a harrow beam or bar 5 which is preterably a Hat bar provided with a plurality ot longitudinal slots 6 and to the upper' edge of thesaid bar, at the center thereof, I secure an arched or curved hanger or bracltl 7. At the center of the said bar, l secure tor pivotal movement a post 8 which extends upwardly past the bracket 7 and carries an eye S) through 'which the intermediate por` row rsa1. sel-iai no. 477,124.

tion of said bracket passesa a set screw l0 being mounted in the eye to bear upon the bracket and thereby secure the same in any set position relative to the post. The upper end oi the post 8 is shown engaged by one end ol a link or couplingl1 which is of an ogee lorm so that it maybe used in connecv tion 'with cultivator beams of various styles.

The coupling link is constructed With forked ends, as shown at l2 in Fig.4 2, and one ot said ends embraces the upper extremity oi the post 8 and is secured thereto by a clamp- .ing bolt 13 inserted through the ends of the forli. .ln the illustrated arrangement, the coupling-is attached to the cultivator beam 8 by having the orlrl?j remote from the post fitted over the cultivator beam and clamped thereto by a bolt lelf. It may sometimes, how* ever, be impractical to connect the `post to thev beam in the describedmanner and the desired connectionmay then be effected by an eye bolt engaged around the post and clamped to the beam orby any other convenient or preferred connection.

The harrow teeth 15 are preferably oit the spring tooth type and are constructed with stra ight upper shanlrs 16 adapted to tit close against the front side of the harroW bar 5 and at their extremities are constructed with hooks 17 which are adapted to engage over the upper edge of the bar and thereby aid in retaining the harrows in engagement With the bar. The central harrovv tooth Will obviously be disposed in juxtaposition to the post 3 and this tooth Will, therefordhave its upper end provided merely with a lug 18 which bears upon the upper edge of the harbar. Clips or Ubolts 19 are iitted around the shanks olf the harrow teeth and through the rslots t; of the harroW bar and are secured in position by nuts mounted upon their extremities and turned home against Washers or plates 2O fitted against the rear side ol. the harroiv bar and bridging the slots 6 through which the respective clips pass. y When the nuts are turned home, the clips will be drawn closely around the shanls of the barrow teeth and the said shanks will 'thereby be itirmly clamped against the barrow bar, as Will be readily understood on reference to Fig. 3.

The harroiv bars are illustrated in Fig. l as line oi' the cultivator, but it will be understood that they` 'may be set to converge toward said line by loosening the bolts 13 and diverging' from the central longitudinal it. will be ound highly then turning the posts 8 about their own longitudinal axes, after which the bolts 13 are again tightened. It is also possible to set either end of either harrow bar above or below the opposite end of the bar by loosening the set screw l() and'then shifting tliebar relative to the post 8 pivotally labout the bolt 2l which attaches the bar to the post. After the desired inclination of the harrow bar has been attained, the set screw 10 is turned `home so as to secure the parts in `the position to which they have been adjusted. r As the machine is drawn over a held7 the harrow teeth will push aside all large stones,

. trash, or other obstacles, and will serve to break up clods and thoroughly pulverize the soil'so'that tlie desired mulch will be produced. lhe cultivatoi shovelsiiollowing in the paths of the respective harrows will turn the pulverized soil over onto the seed or around the stems of young plants so that -they will be protected and growth proinoted. The attachment is very simple in the construction and arrangement oi` lits parts and may beproduced and applied to any cultivator at .a low cost. In operation purposes for which it is designed. yObviously, the harrow teeth may beset closer 'together or fartherrapart by adiusting them efficient for the from end to end of ythe respective slots 6 in the harrow bar andthe construction of the upper extremities of the Shanks of the vhai-row teeth will tend to prevent dropping of the teeth even if the clip bolts by which they are held to the harrow bar should become loosened.

e vHaving thus described the invention, what is claimed as new is:

l. A harrow attachment `for cultivators comprising a harrow bar, harrow teeth car- L). A harrow attachment for cultivators Y comprising` a harrow bar, harrow teeth carried by said bar, a post rising from said bar,

and an ogee coupling link provided at its 4ends with forks, one of said forks beingadapted to embrace and be secured to the Y post andthe otherof said forks being adapted toembrace and besecui'ed to a cultivator beam.

In testimony whereof I alii); my signature.
